Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of geological grouting reinforcement, and particularly relates to an engineering geological grouting reinforcement device. BACKGROUND

[0002] In the field of engineering geology, grouting reinforcement is a crucial technical means, which is widely used in the reinforcement and stability treatment of various geological structures, such as building foundation reinforcement, tunnel engineering, slope protection, underground engineering and many other scenes. By injecting specific grout into the interior of the geological structure, the geological cracks are filled, the density and strength of the geological body are improved, and the stability and bearing capacity of the geological structure are enhanced.

[0003] However, the existing engineering geological grouting reinforcement device has many problems in actual application, which seriously affects the effect and quality of grouting reinforcement.

[0004] In terms of grouting operation, the traditional grouting method is relatively single, usually inserting the grouting pipe into the geological hole and continuously grouting, lacking effective pressure control and grout distribution adjustment means. This leads to the difficulty of grout to fully and uniformly penetrate into various parts of the geological structure, especially in some complex geological conditions, such as the existence of multiple layers of different nature soil or rock fissures, the grout can only fill part of the larger cracks, and it is difficult to effectively reach some small cracks and weak areas, so that the overall strength of the grouting reinforced geological structure is limited, and the ideal reinforcement effect cannot be achieved.

[0005] In summary, the existing engineering geological grouting reinforcement device cannot meet the strict requirements of grouting reinforcement effect and quality under complex geological conditions. Therefore, it is of great practical significance to develop a new type of engineering geological grouting reinforcement device to solve these problems in the prior art. SUMMARY

[0008] An output end of the liquid injection pump is fixedly connected with a mixed liquid supply mechanism which is fixedly connected with the mounting frame, and the mixed liquid supply mechanism is used for mixing and supplying grouting liquid.

[0009] Further, the opening and closing mechanism comprises a mounting groove formed in the pressure injection pipe, a transmission column is slidingly connected in the mounting groove, a spring is fixedly connected to the top end of the transmission column and fixedly connected with the mounting groove, and a sealing plate is fixedly connected to the bottom end of the transmission column.

[0010] Further, the bottom end of the pressure injection pipe is fixedly connected with a flushing pipe, and a plurality of flushing holes are formed in the outer surface of the flushing pipe.

[0011] Further, the mixed liquid supply mechanism comprises a mixing box fixedly connected with the mounting frame, a connecting pipe is fixedly connected to the bottom of the mixing box and fixedly connected with the liquid injection pump, a first rotary driving element is fixedly connected to the bottom of the mixing box, an output end of the first rotary driving element is fixedly connected with a mounting shaft which is rotatably connected with the mixing box, a transmission box is fixedly connected to the top end of the mounting shaft, a plurality of spiral rods are rotatably connected to the transmission box, a plurality of stirring shafts are rotatably connected to the transmission box, a plurality of stirring plates are fixedly connected to the outer surface of the stirring shafts, a transmission mechanism is transmissionally connected to the outer surface of the spiral rods and the stirring shafts and connected with the transmission box, and the transmission mechanism is used for driving the spiral rods and the stirring shafts to rotate.

[0012] Further, the transmission mechanism comprises a second rotary driving element fixedly connected with the transmission box, a first transmission shaft is fixedly connected to the output end of the second rotary driving element, a first bevel gear is fixedly sleeved to the outer surface of the first transmission shaft, two second bevel gears are meshingly connected to the outer surface of the first bevel gear, a second transmission shaft is rotatably sleeved to the middle of the second bevel gears and rotatably connected with the transmission box, a third bevel gear is fixedly sleeved to the outer surface of the spiral rods and the stirring shafts, and a fourth bevel gear is meshingly connected to the second transmission shaft and fixedly sleeved to the third bevel gear.

[0016] Compared with the prior art, the engineering geology grouting reinforcement device has the following beneficial effects:

[0017] The engineering geology grouting reinforcement device significantly improves the grouting reinforcement effect through unique design and operation process. During the grouting process, the second telescopic driving element drives the injection pipe to move up and down reciprocally, and cooperates with the injection pump to pressurize, so that the slurry can be injected into the reinforced geological position in a larger area and in depth. First, the slurry is injected by the injection pipe under pressure, so that the slurry enters the reinforced gap under the action of pressure; after a period of injection, the injection pipe moves down, the sealing plate is blocked under the action of the spring, preventing the slurry from flowing back, and at the same time, the injection pipe moves down to extrude the slurry, further increasing the extrusion pressure, so that the slurry can more fully fill the geological gap. Such reciprocating operation can fully grout the reinforced geological position, effectively enhance the stability and strength of the geological structure, greatly improve the quality and reliability of the grouting reinforcement, and meet the reinforcement requirements under complex geological conditions.

[0018] The device has an automatic flushing function, which greatly facilitates the maintenance and use of the equipment. After reinforcement is completed, the grouting machine stops supplying slurry, the mixed liquid supply mechanism supplies cleaning water to the injection pump, and the injection pump supplies the cleaning water to the injection pipe through the hose. After the water enters the flushing pipe, it is sprayed out through the flushing hole under the action of pressure, and the surface of the grouting pipe is flushed. At the same time, the injection pipe moves up and down reciprocally in the injection pipe, which can fully and automatically flush the surface of the injection pipe, effectively preventing the slurry from solidifying on the grouting pipe. This design avoids equipment failure and blockage caused by slurry residue, prolongs the service life of the equipment, reduces the trouble and workload of manual cleaning, ensures that the grouting pipe can maintain good condition for next use, and improves the use efficiency and convenience of the equipment.

[0019] The first rotating driving member drives the transmission box to rotate, so that the spiral rod, the stirring shaft and the stirring plate rotate as a whole to preliminarily stir the raw materials in the mixing box. Meanwhile, the second rotating driving member drives the stirring shaft and the spiral rod to rotate independently through a series of bevel gears. The stirring plate on the stirring shaft stirs the raw materials in detail, and the spiral rod rotates back and forth to realize the up-and-down reciprocating conveying of the raw materials. This double stirring mode breaks the limitation of the traditional single stirring, makes the raw materials of different levels fully contact and mix, makes various grouting liquid raw materials uniformly mixed, effectively avoids the problem of uneven local raw material concentration, and significantly improves the quality and performance of the slurry, provides a higher quality and more stable material basis for subsequent engineering geology grouting reinforcement, and guarantees the effect of grouting reinforcement.
